+ * Unlike the atrocity that BSD ended up using, we do not have a "union
+ * wait," although I could probably implement one.  Given the code I
+ * sometimes end up porting, it might be a good thing.  Anyway, the
+ * format of a stat thingy, filled in by the wait*() routines, is:
+ * struct {
+ *    int filler:16;
+ *    union {
+ *        struct stopped {
+ *            int signo:8;
+ *            int o177:8;	// will be 0177 
+ *        };
+ *        struct exited {
+ *            int retval:8;
+ *            int zero:8;	// 0, obviously 8-)
+ *        };
+ *        struct termed {
+ *            int zero:8;	// zeroes
+ *            int corep:1;	// was there a core file?
+ *            int signo:7;	// what?!  Only 127 signals?!
+ *        };
+ *        int value:16;
+ *     };
+ * };
+ *
+ * Braver souls than I can turn that into a union wait, if desired.  Ick.
